Abstract
A hybrid drive is disclosed comprising a head actuated over a disk, and a non-volatile semiconductor memory (NVSM). When booting the hybrid drive in a first boot mode, the disk remains spun down, and when booting in a second boot mode, the disk is spun up. In one embodiment the hybrid drive receives a host command that configures the boot mode, and in another embodiment the hybrid drive determines the boot mode based on a state of the NVSM, such as an amount of free space or life remaining of the NVSM.
